I needed a California King due to my height. I thought this was the solution. The problem is, this bed cannot hold air. Within a few hours, the bed looses 30%-40% of its air. I wake just a few hours after going to sleep with horrible back pain due to this dramatic air loss. Sleep Number offers a variety of solutions at SEVERAL HUNDREDS of dollars each. No thank you. I've wasted enough money, Sleep time and frustration trying to resolve all the issues with this bed.
